Short Description

open_iA is a modular open source software tool for the visual analysis and processing of volumetric datasets, with a focus on industrial CT datasets.

As graphical user interface the cross-plattform framework Qt is used, which facilitates an easy to use and attractive interface. In-house visualisation and image processing algorithms are supported by algorithms of the ITK and VTK toolkit, which make open_iA a powerful tool for both 3D visualisation and CT data analysis. open_iA is capable of loading various volume dataset formats as well as different surface model formats. It provides slice by slice navigation in its 2D views, common 3D navigation with arbitrary cutting planes in the 3D view, together with custom views for individual visualization. open_iA provides command line access as well as interfaces to various libraries in terms of image processing, segmentation, registration, feature extraction, visualization, immersive analytics as well as machine learning. open_iA is easily extensible and serves as central development platform of the research group computed tomography and therefore integrates all algorithms and methods developed within the group.
